Abstract: Disclosed are improved processes for making high molecular weight polybutylene terephthalate resin. The PBT resin has a number average molecular weight of 30000 and 55000 g/mol, an IV of between 1.10 and 1.25 dl/g and a carboxylic acid end group concentration of between 35 and 70 mmol/kg. The PBT resin is prepared from PBT oligomers having an intrinsic viscosity of between 0.10 and 0.13 dl/g and a CEG of between 80 and 110 mmol/kg. The oligomers are prepared from purified terephthalic acid and 1,4-butane diol in the presence of a catalyst.
